Topicality

Heat resistant steel 15H12N2MVFAB-sh (sh EP517) — one of the most popular in the metal market. Smelted in an open electric arc furnace. Its composition (in accordance with GOST 5632−72) contains about 12% chromium, tungsten, molybdenum, niobium, vanadium up to 1% carbon and 0.15%, in hundredths of a percent — phosphorus, sulfur and other components.

Technological processing

Circles are made by conventional hot-diameter from 5 to 270 mm, but most manufacturers are on different orders, may change these dimensions. Alloy bad cold deformation is available. When the hot plastic deformation temperature range is 1180 — 900 º C. Hardening the metal is at 1070 º C, the cooling is accomplished in air, oil or water. There is another method, involving cooling with water, followed by aging products for 4−5 hours. Welding parts by means of electrodes 19 marks CT. The machining process due to the high propensity of the metal work-hardening, work is carried out at low speeds with the mandatory use of the tool, which is equipped with carbide or high speed steel plates.

Use

Pipe can withstand in high-temperature above 1000 ° C. The chromium content in the alloy provides high resistance to gas corrosion. Welded structures are designed for long-term operation in the petroleum refining, gas processing and chemical industry with about 1,000 t º º C. This alloy is used not only in the production of pipes of different dimensions, but in the manufacture of heat exchangers, tanks, etc.
